Angry Zoa

[wvfeefkeeper80]

Hey all! My first post, and I’m super excited to be here. I’ve had a tank up and running for ~5 months now and for the most part, all is well. One of my zoa has been really grumpy. I’m thinking a hermit did some much needed cleaning and I did pull a sponge out of it. See anything of particular interest though?

Fluval Marine 32.5 tank. Perimeters are spot on. Salinity at ~34.7 and water changes every week.

The algae is bugging it and they look rather malnourished maybe try dipping them in an iodine solution and removing the algae...then set them in a lower light area

Thanks! I do feed them Reefroids and she’s been open and gorgeous up to now. All others doing well. My calcium was about 550 ppm. Could this hurt zoa? Removal seems problematic as it’s grown onto the rock. Any other, less invasive options you may be able to suggest?

can you pull the rock it's on out of the water? might be easier to remove algae that way and spray some hydrogen peroxide on it to keep it away.

This is the rock it’s on.

I think I could definitely turn my lighting down though. It hits 100% at it highest and I would think 75% would be more than life sustaining whilst combating algae. It’s been my curse.

You can (during a water change) drain the water then put some hydrogen peroxide in a spray bottle once the rocks is exposed spray it and let it sit for 5 min then add the new water... h2o2 will just disappear and it won’t hurt anything once the new water is in

Brilliant tactic! The hydrogen peroxide won’t harm anything but the algae? Is there a chemical reason for this? Thanks in advance! Always wanna lean on experienced advice!

Still be careful to just keep it on the rocks and remove as much algae by hand first.

I switched tanks about a month ago and scrubbed and H202 all my rocks prior to putting them in the new tank. Doesn't hurt to let the peroxide sit on the area for a few minutes either before rinsing off with RO water or tank water.
